Question

Explain how Galileo inferred that objects in vacuum fall with uniform acceleration, and that force is not necessary to sustain horizontal motion. (PLEASEEE BADLY NEED IT NOW)

Answer 1

Galileo inferred that objects in vacuum fall with uniform acceleration because he wanted to explain the concept of feather. as we know that feathers are very light and because of air resistance they fall very slowly. so by removing the air he was able to explain that everthing fall with se acceleration 9.8m/s*s
